This is a professional watch movement holder specifically designed for the ETA Caliber 7750/7751 chronograph movement, with full compatibility extending to 7753 and 7754 variants. Machined from durable aluminum alloy with precision tolerances, it features an 18mm central aperture and adjustable peripheral screws/pins for secure positioning during servicing .
The holder provides stable support for the movement‘s 30.00mm diameter, 7.90mm height dimensions , making it an essential tool for watchmakers performing disassembly, assembly, and maintenance on these complex chronograph calibers.
Q1: Why do I need a dedicated holder for the 7750 movement?
A: The ETA 7750 is a complex chronograph movement measuring 30.00mm in diameter and 7.90mm in height . A dedicated holder ensures the movement is securely positioned during disassembly of the chronograph module, automatic module, and gear train. Using a generic holder may not provide adequate stability for the intricate work required on this movement.
Q2: What should I check before using this holder?
A: Before first use, inspect the holder for:
Sharp edges or burrs that could scratch the movement plate
Smooth operation of all adjustment screws
Correct alignment of the central aperture
Any manufacturing debris
Test-fit a scrap movement (if available) before working on a valuable caliber.
Q3: Can this holder be used for hand-winding variants like the 7760?
A: The 7760 is the hand-winding version of the 7750 (no automatic module) . While it shares similar dimensions, the thickness differs. This holder is specifically designed for the automatic 7750 series (7.90mm height). For hand-winding variants, verify fitment before use.
